Phys.org / Svalbard polar bears show improved fat reserves despite sea ice loss
The body conditions of polar bear (Ursus maritimus) populations around the Norwegian island of Svalbard have improved despite sea ice losses, according to new findings. The findings differ from previously published observations ...
Phys.org / Why hospitality skills can help all businesses adapt to the AI revolution
The future of work is being rewritten by artificial intelligence (AI)—but technology competence alone will not be enough to empower the workforce of the future. While AI has massive potential to improve efficiency, accuracy, ...
Phys.org / Unusual RNA caps reveal previously unknown mechanism of genetic transcription
Scientists at IOCB Prague are uncovering new details of gene transcription. They have identified a previously unknown molecular mechanism by which the transcription of genetic information from deoxyribonucleic acid (DNA) ...
Phys.org / Study shows insect farming byproduct boosts soil health, reduces crop damage
With insect farming projected to produce millions of tons of insects in the coming years, Arkansas Agricultural Experiment Station researchers offer evidence that the insect farming byproduct called "frass" can improve soil ...
Phys.org / Scientists just mapped the family tree of all 11,000 bird species—and you can explore it
The Cornell Lab of Ornithology today announced the release of a new online tool for studying biodiversity and the evolutionary relationships among birds: the illustrated Birds of the World Phylogeny Explorer. Available on ...
Phys.org / From stellar engines to Dyson bubbles, alien megastructures could hold themselves together under the right conditions
New theoretical models have strengthened the case that immense, energy-harvesting structures orbiting their host stars could exist in principle in distant stellar systems. With the right engineering precautions, calculations ...
Phys.org / Amazon Leo satellites exceed brightness limits, study finds
Seeing a satellite zip across the night sky can be a fascinating sight. However, what may be spectacular for people on the ground is becoming a major problem for astronomers. A new study published on the arXiv preprint server ...
Medical Xpress / Expert warning over hidden health effects of US trade tariffs
Greater attention must be paid to both the direct and indirect health effects of trade tariffs including access to medicines, food costs, and employment conditions, say researchers. The U.S. government's assertive use of ...
Phys.org / The Sierra snowpack is dropping fast: Experts say it's not as bad as it seems
The Sierra Nevada snowpack, the source of nearly one-third of California's water supply, is looking a little like a New Year's resolution: full of hope and promise at the beginning of January, but now struggling with a bothersome ...
Phys.org / How tree rings help scientists understand disruptive extreme solar storms
Scientists have long relied on tree rings to learn about ancient solar storms—rare bursts of high-energy particles from the sun that can disrupt satellites, power grids, and communication systems across the planet. When ...
Phys.org / The Great Mongolian Road: Japanese Imperial Army maps reveal first detailed documentation
In a study published in the Journal of Historical Geography, researchers Dr. Chris McCarthy and his colleagues have documented, for the first time, the Great Mongolian Road, a major yet understudied east-west caravan route ...
Medical Xpress / One in 1,000 dies: Framing matters for communicating medical numbers, experts say
Similar—yet not the same: Many studies show that patients often struggle to interpret numerical information in medical contexts, especially probabilities related to recovery and side effects. In a recently published Letter ...
